Subaru launches new Impreza WRX STI Spec C in Japan

Subaru automobiles, today launches the “Subaru Impreza WRX STI spec C”, a new addition to the current WRX STI line-up. The model goes on sale today through Subaru dealerships in Japan.

Based on the Impreza WRX STI, the iconic sport model of Subaru, the WRX STI spec C model features enhanced engine and chassis performance as well as a lighter body on the premise of driving in motor sports. The model further strengthens its presence in the high performance car arena by offering sheer excitement and unique driving sensations as a distinctive road sport model, in line with the performance level originally delivered by the Impreza WRX STI.

The turbocharger newly adopted ball bearings for the turbine axle bearing, and the ECU (Engine Control Unit) program was also exclusively tuned. Thus the engine of the spec C model provides quicker response and improved accelerating performance. Thanks to its specially designed front & rear suspensions and improved body rigidity, the chassis offers stable and linear driving control even in marginal driving conditions. The adoption of an aluminum engine hood, laminar window glasses and a downsized battery resulted in a lighter body, which further polishes the model’s driving performance.

Subaru enhanced the WRX STI line-up by introducing this STI spec C model, in addition to the STI A-Line model, the AT version introduced in February this year.

Outline of Subaru Impreza WRX STI spec C

Enhancement of Engine performance:

Ball bearings of the turbine axle were newly adopted to reduce friction in the turbocharger. With the optimized ECU programming, the engine offers smoother and quicker response to the accelerator pedal and excellent accelerating performance.

An inter-cooler water spray prevents rise in intake-air temperature at continued high-load driving, providing stable engine performance and improved efficiency.

Enhancement of Chassis performance:

Reinforcement of the cross member in front-suspensions offers a linear steering response.
